Action tips: body closed to table, pose attacking before stroking, when the ball bounces from table, arms forward to hit the ball. If the incoming ball is backspin, racket backward, hit the middle and under parts of the ball, push the net quickly; if the incoming ball is non-spin, the racket should be almost vertical with table, often using leveraging or reducing-power to hit the middle part of ball, don’t require hit actively .
